Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479940, here are decompositions:

31 + 33479909 = 33479940
61 + 33479879 = 33479940
71 + 33479869 = 33479940
79 + 33479861 = 33479940
127 + 33479813 = 33479940
149 + 33479791 = 33479940
163 + 33479777 = 33479940
167 + 33479773 = 33479940

Showing the first eight; more decompositions exist.
